Cardiovascular Safety of Febuxostat or Allopurinol in Patients with Gout.

Background: Cardiovascular risk is increased in patients with gout. We compared cardiovascular outcomes associated with febuxostat, a nonpurine xanthine oxidase inhibitor, with those associated with allopurinol, a purine base analogue xanthine oxidase inhibitor, in patients with gout and cardiovascular disease.

Methods: We conducted a multicenter, double-blind, noninferiority trial involving patients with gout and cardiovascular disease; patients were randomly assigned to receive febuxostat or allopurinol and were stratified according to kidney function.

Examining Lead Exposures in California through State-Issued Health Alerts for Food Contamination and an Exposure-Based Candy Testing Program.

In California, the annual number of children under age 6 y of age with blood lead levels (BLL) ≥10μg/dL is estimated at over 1,000 cases, and up to 10,000 cases when BLL between 4.5 and 9.5 μg/dL are included.

Evaluation of machine learning algorithms and structural features for optimal MRI-based diagnostic prediction in psychosis.

A relatively large number of studies have investigated the power of structural magnetic resonance imaging (sMRI) data to discriminate patients with schizophrenia from healthy controls. However, very few of them have also included patients with bipolar disorder, allowing the clinically relevant discrimination between both psychotic diagnostics. To assess the efficacy of sMRI data for diagnostic prediction in psychosis we objectively evaluated the discriminative power of a wide range of commonly used machine learning algorithms (ridge, lasso, elastic net and L0 norm regularized logistic regressions, a support vector classifier, regularized discriminant analysis, random forests and a Gaussian process classifier) on main sMRI features including grey and white matter voxel-based morphometry (VBM), vertex-based cortical thickness and volume, region of interest volumetric measures and wavelet-based morphometry (WBM) maps.

Epidemiologic burden of hospitalisation for congestive heart failure among adults aged ≥19 years in the Philippines.

Objectives: The study determined the prevalence of hospitalisation due to congestive heart failure (CHF) among adult patients aged 19 years and above in the Philippines and its 17 regions in 2014. It also determined the demographic profile of these patients, aetiology and type of CHF, comorbidities, duration of hospitalisation and the overall in-hospital mortality rate.

Methods: Data collection was done using the hospitalisation claims database of the Philippine Health Insurance Corporation (PhilHealth).

Protocol for qRT-PCR analysis from formalin fixed paraffin embedded tissue sections from diffuse large b-cell lymphoma: Validation of the six-gene predictor score.

As a part of an international study on the molecular analysis of Diffuse Large B-cell Lymphoma (DLBCL), a robust protocol for gene expression analysis from RNA extraction to qRT-PCR using Formalin Fixed Paraffin Embedded tissues was developed. Here a study was conducted to define a strategy to validate the previously reported 6-gene (LMO2, BCL6, FN1, CCND2, SCYA3 and BCL2) model as predictor of prognosis in DLBCL. To avoid variation, all samples were tested in a single centre and single platform.

The effect of biological heterogeneity on R-CHOP treatment outcome in diffuse large B-cell lymphoma across five international regions.

Addressing the global burden of cancer, understanding its diverse biology, and promoting appropriate prevention and treatment strategies around the world has become a priority for the United Nations and International Atomic Energy Agency (IAEA), the WHO, and International Agency for Research on Cancer (IARC). The IAEA sponsored an international prospective cohort study to better understand biology, treatment response, and outcomes of diffuse large B-cell lymphoma (DLBCL) in low and middle-income countries across five UN-defined geographical regions. We report an analysis of biological variation in DLBCL across seven ethnic and environmentally diverse populations.

Positive Quantitative Relationship between EMT and Contact-Initiated Sliding on Fiber-like Tracks.

Epithelial-mesenchymal transition (EMT) is a complex process by which cells acquire invasive properties that enable escape from the primary tumor. Complete EMT, however, is not required for metastasis: circulating tumor cells exhibit hybrid epithelial-mesenchymal states, and genetic perturbations promoting partial EMT induce metastasis in vivo. An open question is whether and to what extent intermediate stages of EMT promote invasiveness.

Quality assessment and improvement of post graduate family medicine training in the USA.

Background: In 2013, the World Organisation of Family Doctors published training standards for post-graduate medical education (GME) in Family Medicine/General Practice (FP/GP). GME quality has not been well-defined, other than meeting accreditation standards. In 2009, the Association of Family Medicine Residency Directors (AFMRD) developed a tool that would aid in raising the quality of family medicine residency training in the USA.

CARD9 impacts colitis by altering gut microbiota metabolism of tryptophan into aryl hydrocarbon receptor ligands.

Complex interactions between the host and the gut microbiota govern intestinal homeostasis but remain poorly understood. Here we reveal a relationship between gut microbiota and caspase recruitment domain family member 9 (CARD9), a susceptibility gene for inflammatory bowel disease (IBD) that functions in the immune response against microorganisms. CARD9 promotes recovery from colitis by promoting interleukin (IL)-22 production, and Card9(-/-) mice are more susceptible to colitis.

Retrospective seroepidemiological study of chikungunya infection in South Asia, Southeast Asia and the Pacific region.

Chikungunya virus (CHIKV) and Ross River virus (RRV) of the genus Alphavirus, family Togaviridae are mainly transmitted by Aedes mosquitoes and the symptoms they cause in patients are similar to dengue. A chikungunya (CHIK) outbreak re-emerged in several Asian countries during 2005-2006. This study aimed to clarify the prevalence of CHIKV infection in suspected dengue patients in six countries in South Asia and Southeast Asia.

Ketamine augmentation for outpatients with treatment-resistant depression: Preliminary evidence for two-step intravenous dose escalation.

Objective: Preliminary evidence supports the safety and efficacy of subanesthetic ketamine as an experimental antidepressant, although its effects are often not sustained beyond one week. Studies are lacking that have examined the sustained effects of escalating ketamine doses as augmentation in outpatients with treatment-resistant depression. Therefore, the aims of this study were twofold: (1) to assess the safety and antidepressant efficacy of two-step, repeated-dose ketamine augmentation and (2) to assess the duration of ketamine's antidepressant efficacy as augmentation to ongoing antidepressant pharmacotherapy for 3 months after the final infusion.

Higher measured moisture in California homes with qualitative evidence of dampness.

Relationships between measured moisture and qualitative dampness indicators (mold odor, visible mold, visible water damage, or peeling paint) were evaluated using data collected from California homes in a prospective birth cohort study when the infants were 6 or 12 months of age (737 home visits). For repeated visits, agreement between observation of the presence/absence of each qualitative indicator at both visits was high (71-87%, P < 0.0001).

Conjunctival fibrosis and the innate barriers to Chlamydia trachomatis intracellular infection: a genome wide association study.

Chlamydia trachomatis causes both trachoma and sexually transmitted infections. These diseases have similar pathology and potentially similar genetic predisposing factors. We aimed to identify polymorphisms and pathways associated with pathological sequelae of ocular Chlamydia trachomatis infections in The Gambia.

Intellectual and physical activities, but not social activities, are associated with better global cognition: a multi-site evaluation of the cognition and lifestyle activity study for seniors in Asia (CLASSA).

Background: population ageing will lead to a leap in the dementia population in Asia. However, information about potentials for low-cost and low-risk interventions is limited.

Objectives: to study the associations between lifestyle activities and global cognition from the Cognitive and Lifestyle Activity Study for Seniors in Asia (CLASSA).

Hybrid Vibrio cholerae El Tor lacking SXT identified as the cause of a cholera outbreak in the Philippines.

Unlabelled: Cholera continues to be a global threat, with high rates of morbidity and mortality. In 2011, a cholera outbreak occurred in Palawan, Philippines, affecting more than 500 people, and 20 individuals died. Vibrio cholerae O1 was confirmed as the etiological agent.

Isolation of acanthamoeba genotype t4 from a non-contact lens wearer from the Philippines.

We report the case of a 76-year old Filipino male who presented with pain, redness, and blurring of vision of the right eye. Corneal scraping was done and sent to the St. Luke's Research and Biotechnology Group for detection and identification of the infectious agent.

Prospective international cohort study demonstrates inability of interim PET to predict treatment failure in diffuse large B-cell lymphoma.

Unlabelled: The International Atomic Energy Agency sponsored a large, multinational, prospective study to further define PET for risk stratification of diffuse large B-cell lymphoma and to test the hypothesis that international biological diversity or diversity of healthcare systems may influence the kinetics of treatment response as assessed by interim PET (I-PET).

Methods: Cancer centers in Brazil, Chile, Hungary, India, Italy, the Philippines, South Korea, and Thailand followed a common protocol based on treatment with R-CHOP (cyclophosphamide, hydroxyadriamycin, vincristine, prednisolone with rituximab), with I-PET after 2-3 cycles of chemotherapy and at the end of chemotherapy scored visually.

Results: Two-year survivals for all 327 patients (median follow-up, 35 mo) were 79% (95% confidence interval [CI], 74%-83%) for event-free survival (EFS) and 86% (95% CI, 81%-89%) for overall survival (OS).

Frequency of interleukin 28B rs12979860 C>T variants in Filipino patients chronically infected with hepatitis B virus.

Hepatitis B virus (HBV) is one of the most prevalent viral infections worldwide. Nearly 400 million individuals are chronic carriers of HBV. The aim of the present study was to determine the frequency of human interleukin 28B (IL28B) variants among treatment naive Filipino patients clinically diagnosed with chronic hepatitis B (CHB), and to compare the IL28B frequency distribution with various ethnic populations.

Genetic variation I148M in patatin-like phospholipase 3 gene and risk of non-alcoholic fatty liver disease among Filipinos.

Genome-wide association studies have shown that a non-synonymous single nucleotide polymorphism characterized by a C-to-G change encoding an isoleucine-to-methionine substitution at amino acid position 148 in the human patatin-like phospholipase 3 (PNPLA3) gene was found to be associated with non-alcoholic fatty liver disease (NAFLD) and advanced liver damage. A hospital-based study was conducted to determine the distribution of PNPLA3 genotypes among patients clinically diagnosed and histologically confirmed with NAFLD and among normal controls. We also compared the allelic frequencies of PNPLA3 with different ethnic populations.

Complete genome sequence of chikungunya virus isolated in the Philippines.

Chikungunya virus is an alphavirus of the Togaviridae family, which causes a febrile illness with arthralgia in humans. We report here on the complete genome sequence of chikungunya virus strain CHIKV-13-112A isolated from a patient in the Philippines who was suspected to have dengue virus. Phylogenetic analysis revealed that the strain is of the Asian genotype.

Tanay virus, a new species of virus isolated from mosquitoes in the Philippines.

In 2005, we isolated a new species of virus from mosquitoes in the Philippines. The virion was elliptical in shape and had a short single projection. The virus was named Tanay virus (TANAV) after the locality in which it was found.

Assessing capacity in psychiatric patients with acute medical illness who refuse care.

Three cases are presented that demonstrate the difficulty of assessing medical decision-making capacity in patients with psychiatric illness who are refusing care. Health professionals often assess capacity differently in practice. Provided their patients have some understanding of their illness and have some plans for meeting basic needs, psychiatrists are often inclined to give patients the freedom to refuse care even if they do not exhibit a full understanding of the medical facts of their case and why they are refusing it.
